Name different parts of a nephron. Write absorption and secretion of different parts of a nephron. Nephron: It is the functional part of the kidney‚ encharged of filtration of blood and eliminates the nitrogenous waste of our bodies. The nephron consists of: functional units; two parts: renal corpuscle

the tongue begin the mechanical breakdown of food into smaller pieces. The tongue has taste buds with receptors sensitive to substances. The eye and the olfactory receptors in the nose are important for stimulating the salivary glands in the mouth to secrete saliva. Salivary amylase begins the digestion of starch into maltose. Eventually the semi-solid‚ partially digested food particles are stuck together to form a bolus by the tongue‚ which then pushes it towards the pharynx from where it is swallowed

multigrain bread provided me with carbohydrates. As I take a bite of the peanut butter and jelly sandwich I crush all three of the macronutrients with my teeth. The role of saliva helps moistens the food while a digestive enzyme in the saliva called salivary amylase (ptyalin) helps breaks down the complex carbohydrates mostly contained in the bread into simple sugars. Once the food has been sufficiently chewed‚ the tongue rolls it into a ball known as a bolus and pushes it into the pharynx. In a combination

mono-saccharide molecules which can be easily absorbed by the body. The first step of digestion is the moment we put the food in mouth. As we chew the food‚ the saliva released by the salivary glands of the mouth starts its work of breaking up of the carbohydrates. This is possible because of the presence of a special enzyme named amylase in the saliva. Then we swallow the food and it goes to the stomach. Here the digestive acids secreted by the glands of the stomach play a major role in processing the carbohydrate

still have too few answers to many questions: "Why can we not predict who will get the disease?" "Why do we not become immunized?" "How much saliva is enough?" or "Which salivary components are protective?" and "Which salivary components predispose for caries?" It is generally accepted‚ however‚ that saliva secretion and salivary components secreted in saliva are important for dental health. The final result‚ "caries to be or not to be"‚ is a complex phenomenon involving internal defense factors‚
